2.0.8 Not working with ESP32 Arduino SDK 2.0.2 #56

Closed milGus closed 2 years ago

milGus commented 2 years ago

Release 2.0.8 Works with 2.0.1. However with 2.0.2, we get "Unable to connect to Telegram server"

Update: https://github.com/espressif/arduino-esp32/issues/6077

It appears its a regression in 2.0.2

Workaround:

client.stop(); client.setHandshakeTimeout(30);

Now it works OK.

Thanks @milGus I'm sorry for late reply.

I've implemented the workaround suggested directly in the library inside the checkConnection() method and it works! It will be avalible online soon.

// ESP32 core version 2.0.2 workaround
// https://github.com/espressif/arduino-esp32/issues/6077
#if defined(ESP32)
WiFiClientSecure* _client =  static_cast<WiFiClientSecure*>(telegramClient);
_client->setHandshakeTimeout(30);
#endif

Thanks always happy to help. Btw is there something I can do to help with the GSM/LTE integration?

A working example would be very very apreciated! A user wrote that he was able to work via GPRS and this SSL wrapper with a SIM800 if I remember correctly, but I haven't had any updates from him.
